This is for person whose son's TI had died--


     A couple of days ago, my TI 99/4A died just after loading an assembler
I am working on(LONG program).  I powered it off and then back on again,
after disconnecting my homebrew RAM expansion and speech synthesizer.  That
time the screen went black and the sound generator started putting a high-
pitched wail.

     After opening up the case, I pulled out the power supply board and checked
voltages.  Both +5 and +12 were fine, but -5 was gone.  The CPU and GROM, among
other things, require -5V to work.  I am going to replace the -5V regulator this
weekend and post the results.  I hope the rest is OK.

     By the way, I found out why the black area on the right of the console by
the cartridge port gets so warm:  the power supply sits right there.  I'm
going to see about mounting a fan on my console.

Hope this helps(me,too)!
